UNITED STATES HERMAN J. BQSCH, OF NEW YORK, N. Y.

DRYNG APPLIANCES.

Application led December?, 192GB. Serial No. 48,848.

To all whom z't may concern:

Be it known that l, HERMAN J. BOSCH, a citizen of the United States, residing at New York, in the county of New York, State of New York, have made a certain nenv and useful lnvention in Drying Appliances, of which the following is a specification.

My invention relates to improvements in drying appliances which are useful for drylO in` hair and for other purposes.

he objects of my invention include the provision of. apparatus which is provided with outlets for directing streams of relatively dry and heated air to any place, and which outlets are remote from a motor or source of air, but which are in close proximity to means for heating the air.

Another object of my invention includes the provision of means whereby air may be safely and readily rendered effective for drying and igor other purposes in close proximity to its use or application,

'A still further object of my invention includes means whereby the degree of heating medium is regulated simultaneously with the volume of air supplied to thereby ensure safety against over-heating. y

A still further object includes the provision of means vvhereby the heating and dry-v ing appliance is safe-guarded against direct contact With objects, thereby ensuring safety against accidental damage by over-heating.

Otherqobjects Will appear more fully hereinatter.

ll attain the objects of my invention by the device represented in the accompanying drawing, in vvhich- Fig. 1 represents a plan view ot my appliance with the covers removed, and in which "ill A represents the heating and drying or air directing appliance, and B the supply and regulating; device;

Fig. 2 represents a perspective vievv of the air heating and directing appliance;

Fig. 3 represents a top plan vievv thereof;

Fig. 5 represents an end view of said appliance With they protecting1 cap removed;

Fig. 6 represents a section on lines 6*-6, Fi 3; and

ig. 7 represents a section on line 7 7 of Fic. 1 B.

imilar numerals roter to similar parts of the several vieu- Referring now to the drawing, my invention embraces an air heating and air directing appliance which is composed of a main tube 10, having supporting' ends 11, of insulating material, and being supplied tvith an air inlet duct 12, and air distributing* spray ducts 13. The air duct 12 is connected to any suitable source of supply as pipe lei, for the purpose hereinafter more fully stated. 'Within the air heating or air directingappliance there is provided a suitable heating device, which speciically may be an electrical coil represented at 14e". This coil is properly supported on a central bar 15, and suitably connected to conductor Wires at 16 and 17. The conductor Wires 16 and 17 are led Ain through proper .conduits 18 and 19, and are connected to a suitable regulating device by a socket 20, as will be more fully explained hereinafter. iFhe ends' of my air heating; and air directing` appliance protected by suitable insulating caps 21 and 22. For further protection, the heating and air directing appliance is also provided with a bar 23, and side wings 2e. These latter devices arel for the purpose of guarding' the device against comingr in contact With surfaces, and thereby ,causingdamage when heated.

For regulating.,7 the supply of air and thc heating medium, provideL a specialized valve and switch construction represented ingeneral at B in l. rlhis construction consists of a support 25, provided with an electric switch Q6, for regulating the current supply.y 'llhis switch consists oi'l elongated are shaped contacts 27, and switch blades 28. Switch blades 28 are operated in unison by a cross member 29, which is connected by a link 31 to an operating bar or lever 30 having; a handle 30. rFhe current supply may further be regulated, if desired, by a suitable rheostat represented at 32, which may be operated by hand, or it may, preferably, be operatively connected with lever. 30, by any suitable connections as a lever and ratchet 31', to thereby regulate the current supply simultaneously with the air supplied as may be indicated at 32. The air supply is obtained `from any desired source. as from a motor, or compressed air tank, through a pipe or duct 33. llVithin this duct at 34, there is provided a suitable air valve Which is directly operated by the operating lever 30, as stated above. Tt is apparent from the arrangement of my regulating device at B, that I can simultaneously lregulate the current and air supply in my air heating and air directing appliance at A, by simply adjusting the lever 30 to the position desired.

This arrangement affords the advantage of protection against accidentally turning on the current Without turning on the air supply and thereby over-heating and injuring the device, and while I have, for. the purpose of illustration, shown and described a specific embodiment of my invention, I

l wish it to be understood'that I do not thereby limit myself, as obviously various modiications embracing the spirit and scope of my invention will occur to those versed-in the art.

By my arrangement of the heating coil in the air directing appliance, it is possible to attain the at advantage of having the air relativ;e dry and `heated as it is needed, without anymater'al loss of heat units. I have also the advantage of readily applying the heated air by the specific con-V struction ofl my device wherein the extension of the air duct 12 forms a convenient Having now set forth the objects and nature of my invention, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is:

1. In a drying appliance, the combination of vmeans for simultaneously -supplying air and a heating medium to a heating and distributing appliance remote from the source of air supply, and means for directing and distributing sprays of heated and relatively dry air.

2. In a drying appliance, the combination of means for simultaneously'supplying and regulating airand a heating medium, means for directing' said air and heating medium to an air heating and distributing appliance remote from the source of air supply, means for .heating said air in close proximity to its use, andmeans for directing and distributng sprays of heated air as described.

3. The combination in a drying ap liance of means for simultaneously regu ating drying and heating media together with means for utilizing said media at a point remote from its source.

4. The combination in a drying appliance of means for simultaneously regulating drying and heating mediav together with means for utilizing said media at a point remote from its source, said` means including a heat-ing device in a container and air spray distributing outlets.

5.' The combination in a electric appliance of means for simultaneously regulating an air supply andan electric current supply, means for electrically heat-ing said air supply remote from the source of supply, and means for forming and directing sprays of heated air as described.

' 6. In an air heating and air directing appliance, the combination of a tubular container having a centrally located air inlet duct and a series of air distributing spray ducts and end supports, and means within the container supported by the end supports for heating the air as it passes through said device.

7. In an air heating and directing appliance, the combination of a tubular support having end sup rts andl protective caps, and an electrically)7 heated coil held within said container, and protective guards on said container.

In testimony whereof I have hereunto set my hand on this 17th day of November, A.
